The VG algebra tope-graph reconstruction conjecture
Assume . Let and be real arrangements. Their filtered VG algebras are , and their graded VG algebras are . The VG algebra tope-graph reconstruction conjecture. If
as filtered algebras, or if
as graded algebras, then the tope graphs and are isomorphic. The conjecture would extend the result known in the supplied text for arrangements generic in codimension to general arrangements; the supplied text gives no resolution.
